Leila bought some books. She spent a total of $58 after a discount of $7 off of her total purchase. Each book cost $5. (a) Write an equation that could be used to answer the question above.
First choose the appropriate form. Then, fill in the blanks with the
numbers 58,7, and 5. Let b represent the number of books.

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
